Appreciiable children's ride-on bicycle on the market at present, the external diameter specification of its tire has more than a kind of, and installing and using of auxiliary wheel is not confined on the bicycle that children's ride-on uses completely yet, and the adult rides riding bicycle sometimes also needs to install, and advances with in response to the part consumer demand; Yet, the auxiliary wheel support bar that the past dealer is produced as mentioned above, it all only lands at single kind, and height distance is designed to form, just, it only is applicable to single kind of tire size, if when being contained in the tire of another kind of specification, just must go out the specification product that another is consistent by remanufacturing, so, obviously, cause the raising on the industry cost and do not meet preferable industry applications.
Therefore, fix and have the problem points of applicability limitation at above-mentioned known auxiliary wheel support pole length, how to develop the novel auxiliary wheel support structure that a kind of assembled length can be adjusted, applicability is wider, real be the required improvement breakthrough of industry part.
Summary of the invention
The technical matters that the utility model desire solves is primarily aimed at known auxiliary wheel support pole length and fixes and exist the problem points of applicability limitation to be improved breakthrough.
The technical scheme that the utility model is dealt with problems is as follows: a kind of bicycle auxiliary wheel support structure, and it comprises auxiliary wheel and in order to this auxiliary wheel is assembled in the support at the wheel shaft position of bicycle rear; This support is made up of a group seat-joined and a pole, and this group seat-joined top tool one perforating just can be set in aforementioned wheel shaft, multiple mat nut screw lock location; This auxiliary wheel pivot group is in the pole bottom; It is characterized in that, this group seat-joined bottom be provided with one upright to the embedding chute, this embedding chute bottom is the open state introducing port, the cell wall of embedding chute is provided with upper and lower spaced perforation; This pole top can be inserted in the embedding chute that slips into group seat-joined, and this pole top be provided with knock hole can with arbitrary perforation contraposition mutually of aforementioned embedding chute, utilize bolt to wear assembly again and close nut locking and reach the location.By this, this pole will have scalable adjustment polarization, and can adjust the distance of auxiliary wheel and bicycle quick between centers.
The effect of contrast prior art:
1. a kind of new bicycle auxiliary wheel support structure kenel with scalable adjustment locating features is provided, reaches a kind of novelty purpose that is different from known stationary structure kenel.
2. the particular design of the scalable adjustment of its pole of mat location can be adjusted the distance of auxiliary wheel and bicycle quick between centers, and auxiliary wheel can be assembled on the bicycle that is common to different kinds of tyre external diameter specification, reach the applicability progressive fact more widely; And industry need not be made other specification product of producing again, can significantly reduce its manufacturing cost and has preferable industry applications.
